Integral lifting process for urban viaduct under complex conditions
The invention discloses an overall lifting process for an urban viaduct under complex conditions, belongs to the technical field of overall lifting, and refers to the structural characteristics of the viaduct. The number n of special reaction frames required for lifting this time, the width b1 of a cross beam, the h1 and h2 of supporting seats required by the reaction frames on the two sides and the length b2 of supporting claws of the special reaction frames are calculated according to the positions of web plates in the structure, the distance B1, the heights H1 and H2 required for lifting of the two sides of the viaducts and the distance B2 between the adjacent viaducts. According to the characteristics of the viaduct structure, the position of the gravity center of the structure is preliminarily judged, and in order to guarantee the overall lifting reliability of the viaduct, an upper lifting mode is used for replacing a lower jacking mode, so that the stability of the ramp bridge in the overall lifting process is rapidly and effectively achieved.
本发明公开了一种用于复杂条件下城市高架桥的整体抬升工艺，属于整体抬升技术领域，参考高架桥自身的结构特点，根据结构内部的腹板位置、间距B1、高架桥两侧需抬升的高度H1、H2、相邻高架桥之间的间距B2计算出本次抬升需要的特制反力架数量n、横梁宽度b1、两侧反力架需支座的h1、h2以及特制反力架支撑爪的长度b2。根据上述高架桥结构的特点，初步判断结构重心的位置，为保证高架桥整体抬升的可靠性，利用上部抬升的方式代替下部“顶升”的方式，从而快速有效解决匝道桥整体升降过程中的稳定性。
